In this paper, we review several lines of recent work aimed at developing practical methods
for adaptive on-line stimulus generation for sensory neurophysiology. We consider various …

Both surface luminance and edge contrast of an object are essential features for object
identification. However, cortical processing of surface luminance remains unclear. In this …

The brightness and color of a surface depends on its contrast with nearby surfaces. For
example, a gray surface can appear very light when surrounded by a black surface or dark …

There is ample evidence from demonstrations such as color induction and stabilized images
that information from surface boundaries plays a special role in determining the perception …

The stimulus-response relationship of many sensory neurons is nonlinear, but fully
quantifying this relationship by a complex nonlinear model may require too much data to be …

Glossiness is the visual appearance of an object's surface as defined by its surface
reflectance properties. Despite its ecological importance, little is known about the neural …

Recent theories of lightness perception assume that lightness (perceived reflectance) is
computed by a process that contrasts the target's luminance with that of one or more regions …

To maintain color constancy, the human visual system must distinguish surface reflectance-
based variations in wavelength and luminance from variations due to illumination. Edge …

The primary visual cortex (V1) is extensively studied with a large repertoire of stimuli, yet
little is known about its encoding of natural images. Using voltage-sensitive dye imaging in …

Previous work has demonstrated that perceived surface reflectance (lightness) can be
modeled in simple contexts in a quantitatively exact way by assuming that the visual system …
